The 'Russian Roulette' singer – who was spotted recently on a number of dates with Los Angeles Dodger baseball player Matt Kemp, 25 – has dismissed claims she's in a relationship but is hoping to find true love by the time she's 30.

The 21-year-old pop beauty – who attended the Grammy Awards on Sunday night (31.01.10) alone - said: 'I'm not dating anyone – I'm single. I'm hoping to find love before I'm 30, which is almost a decade away. Even when I was in a relationship, I always have gone alone."

Although she didn't officially attend the prestigious ceremony with Matt, Rihanna was later spotted sneaking the baseball player into an after-party via a back entrance.

It was rumoured she had flown Matt to Abu Dhabi for her New Year's Eve performance (31.12.09) at the Emirates Palace, and the pair were also seen holidaying together in Mexico.

It was after attending a pre-Grammy Awards party in 2009 that Rihanna was left battered and bruised by her then-boyfriend Chris Brown when he assaulted her in his car.
